Abstract The degree to which the original community composition of the Middle Cambrian Burgess Shale was altered through transport and decay and how taphonomic conditions varied through time and across taxa is poorly understood. To address these issues, variation in fossil preservation was analyzed through a vertical succession of 26 bed assemblages, each representing a single obrution event, within the 7-m-thick Greater Phyllopod Bed of the Walcott Quarry. More than 50,000 specimens belonging… Expand
Paleoecology of the Greater Phyllopod Bed community, Burgess Shale
TLDR
Comparisons with Lower Cambrian Chengjiang-type assemblages of southern China suggest that the overall structure and ecology of Cambrian communities remained relatively stable until at least the Middle Cambrian in subtidal siliciclastic soft substrate environments, and with modern marine benthic ecosystems further suggest the Burgess Shale community was probably highly dependent on immigration from a regional pool of species after each burial event.

An Ordovician variation on Burgess Shale-type biotas
TLDR
The early stages of the GOBE is clarified by describing a new open-marine Konservat-Lagerstätte from the Early Ordovician of Wales, which includes many lineages typical of the Cambrian Burgess Shale-type biotas, but the most abundant groups were sponges, algae and worms, with non-trilobite arthropods being unexpectedly rare.

The paleoredox setting of Burgess Shale-type deposits
Abstract Burgess Shale-type (BST) biotas occur globally in Lower and Middle Cambrian shales, and were preserved under specific and exceptional circumstances. Among the circumstances surroundingExpand
Paleocommunity Analysis of the Burgess Shale Tulip Beds, Mount Stephen, British Columbia: Comparison with the Walcott Quarry and Implications for Community Variation in the Burgess Shale
Abstract. The Tulip Beds locality on Mount Stephen (Yoho National Park, British Columbia) yields one of the most abundant and diverse (∼10,000 specimens in 110 taxa) Burgess Shale fossil assemblagesExpand
A new phyllopod bed-like assemblage from the Burgess Shale of the Canadian Rockies.
TLDR
The discovery of an extraordinary new soft-bodied fauna from the Burgess Shale is reported, and the presence of the stem arthropods Misszhouia and Primicaris, previously known only from the early Cambrian of China, suggests that the palaeogeographic ranges and longevity of Burgess Shales taxa may be underestimated. Expand
Substrate adaptations of sessile benthic metazoans during the Cambrian radiation
TLDR
This analysis attempts to constrain the temporal and spatial pattern of the AR and CSR by performing a global-scale paleoecological analysis of the adaptive strategies of benthic fauna living during the Cambrian, demonstrating that most early and middle Cambrian faunas were mixtures of Phanerozoic- and Proterozoic-style adaptive strategists.

Demecology in the Cambrian: synchronized molting in arthropods from the Burgess Shale
TLDR
Evidence for mass molting events in two unrelated arthropods from the Burgess Shale Walcott Quarry, Canadaspis perfecta and a megacheiran referred to as Alalcomenaeus sp. Expand
Deciphering trophic interactions in a mid-Cambrian assemblage
TLDR
A high-resolution fossil data set from Raymond Quarry is presented and a measure of “preservation bias” is formulated that aids identification of assemblage subsets to which network analyses can be reliably applied and demonstrates a shift from specialist interaction-dominated assemblages to ones dominated by generalist and competitive interactions.

The fauna shows that the early evolutionary diversification of Metazoa in the marine environment was along many parallel, distinct lines, in the absence of the more intensive later competition. Expand
